Abstract

Purpose: To evaluate the clinical effect of complete denture restoration in edentulous patients using secondary functional impression.

Methods: Complete denture restoration was performed in 433 edentulous patients using secondary functional impression. The Geriatric Oral Health Assessment Index (GOHAI) was used to evaluate patients' oral health-related quality of life before and after restoration. All patients were divided into 3 groups according to whether they had a history of denture restoration: no denture group(ND)，removable partial denture group(RPD), complete denture group(CD). In CD group, 30 patients were asked to chew two-colour gum. The SDhue value was evaluated by using ViewGum software. SPSS 26.0 software package was used for data analysis.

Results: The oral health-related quality of life was improved in all the 3 groups after restoration, and the GOHAI index 1 month after restoration was significantly higher than that before restoration(P＜0.05). In CD group, SDHue value of 30 patients after restoration was significantly lower than that before restoration(P＜0.05).

Conclusions: Secondary functional impression is simple and fast, and can improve the satisfaction of patients after complete denture restoration.
